Description

Technical Field

[0001] This invention relates to the field of vehicle-mounted equipment technology, and in particular to a ceiling-mounted screen with a novel unlocking and locking structure for suspended ceilings. Background Technology

[0002] A ceiling-mounted screen is an in-vehicle comfort and entertainment device installed on the roof of a vehicle to play multimedia information.

[0003] There are two ways to open a ceiling-mounted screen: manual and electric. To reduce product costs, the manual opening method is usually used.

[0004] like Figure 15 and Figure 16 As shown: A typical manual ceiling-mounted screen includes a mounting base A1 and a display assembly A2. The display assembly A2 is rotatably mounted on the mounting base A1 and has open and closed states. When the ceiling-mounted screen is open, the display assembly A2 is approximately perpendicular to or tilted towards the vehicle roof for easy viewing. When the ceiling-mounted screen is closed, the display assembly A2 is approximately flush with the vehicle roof for easy storage. The mounting base A1 has a locking structure that cooperates with the display assembly, and it also has an unlocking structure that cooperates with the locking structure. The locking structure includes a latch A3, which is movably mounted on the mounting base A1. The display assembly A2 has a lock groove A21 that cooperates with the latch A3. When the display assembly A2 is rotated into position, the locking tongue A3 is inserted into the locking groove A21 under the action of the external elastic element, which can realize the locking operation of the display assembly A2. The unlocking structure includes a button A4 and an unlocking component A5. The button A4 is guided and slidably mounted on the mounting base A1, and the unlocking component A5 is rotatably mounted on the mounting base A1. When the button A4 is pressed, the button A4 can press and drive the unlocking component A5 to rotate. The unlocking component A5 drives the locking tongue A3 to disengage from the locking groove A21. Since the display assembly A2 is relatively heavy, a large holding force of the locking tongue A3 (i.e., the elastic force of the external elastic element) is required. The locking tongue A3 is unlocked by lever, which results in a large pressing force for the button A4, and the operation comfort when opening the display assembly A2 is not enough. Summary of the Invention

[0005] This invention overcomes the shortcomings of the prior art and provides a ceiling-mounted screen with a novel unlocking and locking structure. Its structure is simple and the operation is comfortable when the display assembly is opened.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is: a ceiling-mounted screen with a novel unlocking and locking structure, comprising a mounting base and a display screen assembly rotatably mounted on the mounting base. The display screen assembly is provided with a lock groove, and the mounting base is provided with an unlocking and locking structure that cooperates with the lock groove of the display screen assembly. The unlocking and locking structure includes a latch seat, a button, and a first elastic element. The latch seat is rotatably mounted on the mounting base, and a latch that cooperates with the lock groove is movably provided on the side of the latch seat near the display screen assembly. The button... The guide slide is mounted on the mounting base and located next to the latch seat. The first elastic element can always provide elastic force to the button to slide outward and reset. The latch seat has a stop block near the button, and the button has a limit block near the latch seat. When the button is not pressed inward, the limit block and the stop block abut against each other, thereby restricting the latch seat from flipping away from the display assembly. When the button is pressed inward, the limit block disengages from the stop block, and the latch seat flips away from the display assembly under the action of the display assembly, thus driving the latch to disengage from the lock groove.

[0007] By adopting the above solution, the mounting bracket is suspended from the roof inside the vehicle. When the display assembly is in the open state and the button is not pressed inward, the display assembly is flipped upward to close it until the latch falls into the lock slot of the display assembly, thus completing the closing of the display assembly. Under the action of the first elastic element, the button ensures that its limiting block always abuts against the stop block of the latch seat, preventing the latch seat from rotating away from the display assembly. Therefore, without releasing the contact between the limiting block and the stop block, the display assembly can remain in the closed state. When the display assembly is in the closed state, pressing the button inward causes the limiting block to disengage from the stop block, simultaneously creating space for the latch seat to rotate. The latch seat is then opened by the gravity of the display assembly or by external drive. The elastic force of the opening direction rotation causes the latch seat to flip away from the display assembly. The latch follows the latch seat and flips away from the lock groove. In this way, the display assembly flips down under its own gravity or external elastic force to complete the opening operation. After the display assembly is opened, the button is removed. The button slides back to its original position under the action of the first elastic element. This not only causes the latch seat to flip back towards the display assembly, but also allows the limit block to abut against the stop block again, so that the display assembly can be closed next time. Since the latch seat is not directly flipped by pressing the button, the button operation force is not directly related to the latch holding force. The button operation force and stroke can be determined according to actual needs. Its structure is simple and the operation is comfortable when the display assembly is opened.

[0008] A further feature of the present invention is that the latch is rotatably mounted on the latch seat, the latch is provided with a locking block that cooperates with the lock groove, and also includes a second elastic element. The second elastic element can always provide an elastic force to flip the latch in the opposite direction. During the closing process of the display assembly, the latch is flipped in the forward direction by the pressure of the display assembly.

[0009] By adopting the above solution, the display assembly is flipped up to close. The display assembly will cause the locking tongue to flip forward, which will not affect the closing of the display assembly. Until the display assembly is flipped to horizontal +0.8°, the locking groove is set to the locking tongue. The locking tongue is flipped in the opposite direction by the action of the first elastic element, so that the locking block falls into the locking groove. At this time, the display assembly can be locked. Without pressing the button inward, the display assembly can remain in the closed state. The structure is simple and the design is reasonable.

[0010] A further feature of the present invention is that the button has a guide slope near the limiting block. When the button slides outward under the action of the first elastic element, the limiting block moves to a position that abuts against the stop block through the action of the guide slope.

[0011] By adopting the above scheme, when the button slides outward under the electric force of the first elastic element, the guide slope can first abut against the locking tongue seat. In this way, the button can drive the locking tongue seat to flip and reset towards the display assembly. After the button is reset, the limit block abuts against the stop block again so that the display assembly can perform the closing operation next time. The structure is simple and the design is reasonable.

[0012] A further feature of the present invention is that it includes a limiting structure that restricts the bolt from flipping in the opposite direction when the lock block falls into the lock groove. The limiting structure includes an abutment block that is fixed or integrally disposed on the bolt, and the abutment block abuts against the mounting base or the bolt seat.

[0013] By adopting the above solution, when the display assembly is in the closed state, the display assembly's own weight or external elastic force will give the display assembly a force to flip in the opening direction. The abutment block is located on the rotation trajectory of the lock tongue, and the abutment block can abut against the mounting base or lock tongue seat, thereby restricting the lock tongue from flipping in the opposite direction. In this way, the lock block of the lock tongue will not disengage from the lock groove. Even if the display assembly is subjected to a force to flip in the opening direction, the display assembly can always remain in the closed state. The structure is simple and the design is reasonable.

[0014] A further feature of the present invention is that the first elastic element is a spring, with one end of the spring abutting against the mounting base and the other end of the spring abutting against the button.

[0015] By adopting the above solution, a positioning post or positioning cavity can be set on the button to ensure stable installation of the spring. The structure is simple and the design is reasonable.

[0016] A further feature of the present invention is that: the latch seat is rotatably mounted on the mounting base via a first rotating shaft, and the latch is rotatably mounted on the latch seat via a second rotating shaft. The first rotating shaft and the second rotating shaft are parallel to each other. The second elastic element is a torsion spring. The latch is provided with a mounting shaft, which is arranged along the same central axis as the second rotating shaft. The torsion spring is sleeved on the mounting shaft, with one end of the torsion spring abutting against the latch and the other end of the torsion spring abutting against the latch seat.

[0017] By adopting the above solution, the torsion spring is installed stably, has a simple structure, and is reasonably designed.

[0018] A further feature of the present invention is that: the mounting base is provided with a receiving groove adapted to the shape of the display assembly; one end of the display assembly is provided with a rotating part that rotatably engages with the mounting base; a locking groove is opened on the outer side surface of the other end of the display assembly away from the rotating part; and an opening for the locking tongue to move is provided on the side wall of the receiving groove.

[0019] By adopting the above solution, the rotating part of the display assembly can be rotatably mounted on the mounting base via the third rotating shaft. The receiving groove is adapted to the shape of the display assembly. When the display assembly is in the closed state, it can be stored in the receiving groove. The position of the lock groove is reasonably designed, and the opening is set so that the locking block of the lock tongue can fall into or disengage from the lock groove.

[0020] The present invention will now be further described with reference to the accompanying drawings. Attached Figure Description

Detailed Implementation

[0038] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0039] like Figures 1-14As shown, a suspended ceiling screen with a novel locking and unlocking structure includes a mounting base 1 and a display assembly 2 rotatably mounted on the mounting base 1. The display assembly 2 has a locking groove 21. The mounting base 1 has a locking and unlocking structure that engages with the locking groove 21 of the display assembly 2. The locking and unlocking structure includes a latch seat 3, a button 4, and a first elastic element. The latch seat 3 is rotatably mounted on the mounting base 1. A latch 6, which engages with the locking groove 21, is movably mounted on the side of the latch seat 3 closest to the display assembly 2. The button 4 is guided and slidably mounted on the mounting base 1 and located on the latch. On one side of seat 3, the first elastic element can always provide elastic force to push button 4 outward and reset. Lock tongue seat 3 is integrally provided with stop block 31 near button 4. Button 4 is integrally provided with limit block 41 near lock tongue seat 3. When button 4 is not pressed inward, limit block 41 and stop block 31 abut against each other, thereby restricting lock tongue seat 3 from flipping away from display assembly 2. When button 4 is pressed inward, limit block 41 disengages from stop block 31, and lock tongue seat 3 is flipped away from display assembly 2 by the action of display assembly 2, and drives lock tongue 6 to disengage from lock groove 21.

[0040] In this embodiment, the latch 6 is rotatably mounted on the latch seat 3. The latch 6 has an integrally formed locking block 61 that engages with the lock groove 21. It also includes a second elastic element, which consistently provides a resilient force to the latch 6, causing it to flip in the opposite direction. During the closing process of the display assembly 2, the latch 6 is flipped in the forward direction by the pressure exerted by the display assembly 2. Alternatively, the latch can be mounted on the latch seat by sliding, as long as it allows the latch to fall into the lock groove to achieve the locking operation.

[0041] In this embodiment, the button 4 is provided with a guide slope 42 near the limiting block 41. When the button 4 slides outward under the action of the first elastic element, the limiting block 41 moves to the position of abutting against the stop block 31 through the action of the guide slope 42. In this way, when the button 4 is reset, it can not only drive the locking tongue seat 3 to flip and reset towards the direction of the display assembly 2, but also make the limiting block 41 abut against the stop block 31 again so that the display assembly 2 can perform the closing operation next time.

[0042] In this embodiment, a limiting structure is also included to restrict the reverse flipping of the bolt 6 when the lock block 61 falls into the lock groove 21. The limiting structure includes an abutment block 62 fixedly or integrally disposed on the bolt 6, and the abutment block abuts and cooperates with the mounting base or the bolt seat.

[0043] In this embodiment, the first elastic element is a spring 5, with one end of the spring 5 abutting against the mounting base 1 and the other end of the spring 5 abutting against the button 4. Of course, the first elastic element can also be replaced by other components, as long as they can drive the button to reset.

[0044] In this embodiment, the latch seat 3 is rotatably mounted on the mounting base 1 via a first rotating shaft 32, which is fixedly or integrally mounted on the latch seat 3. The latch 6 is rotatably mounted on the latch seat 3 via a second rotating shaft 63, which is fixedly or integrally mounted on the latch 6. The first rotating shaft 32 and the second rotating shaft 63 are parallel to each other. The second elastic element is a torsion spring 7. A mounting shaft 64 is fixedly or integrally mounted on the latch 6, and the mounting shaft 64 and the second rotating shaft 63 are arranged along the same central axis. The torsion spring 7 is sleeved on the mounting shaft 64, with one end of the torsion spring 7 abutting against the latch 6 and the other end abutting against the latch seat 3. Alternatively, the second rotating shaft and the mounting shaft can be integrally mounted.

[0045] In this embodiment, the mounting base 1 is provided with a receiving groove 11 that matches the shape of the display assembly 2. One end of the display assembly 2 is provided with a rotating part 22 that rotatably engages with the mounting base 1. The rotating part 22 is rotatably mounted on the mounting base 1 via a third rotating shaft 8. A locking groove 21 is formed on the outer surface of the other end of the display assembly 2 away from the rotating part 22. An opening 12 for the locking tongue 6 to move is provided on the side wall of the receiving groove 11. Of course, the locking groove can also be provided in other positions, as long as it can unlock or lock the display assembly.

[0046] Working principle:

[0047] When the display assembly 2 is in the open state and button 4 is not pressed inward, flipping the display assembly 2 upward to close it will cause the display assembly 2 to abut against and drive the latch to flip forward, without affecting the closing of the display assembly 2. Until the display assembly 2 is flipped to horizontal +0.8°, the lock groove 21 is set to the latch 6. The latch 6 is flipped in the opposite direction by the torsion spring 7, so that the lock block 61 falls into the lock groove 21. The abutting block 62 abuts against the mounting base 1 or the latch seat 3, thus locking the display assembly 2 and completing the closing of the display assembly 2. Under the action of the spring 5, the button 4 can keep its limit block 41 abutting against the stop block 31 of the latch seat 3. The latch seat 3 cannot flip away from the display assembly 2. Therefore, without releasing the abutting between the limit block 41 and the stop block 31, the display assembly 2 can always remain in the closed state.

[0048] When the display assembly 2 is in the closed state, press button 4 inward to disengage the limit block 41 from the stop block 31, thus creating space for the locking tongue seat 3 to flip. Under the influence of the gravity of the display assembly 2 or the elastic force of the external drive to rotate the display assembly in the opening direction, the locking tongue seat 3 will flip away from the display assembly 2. The locking tongue 6 will also flip along with the locking tongue seat 3, causing the locking block 61 to disengage from the locking groove 21. In this way, the display assembly 2 will flip down under its own gravity or the external elastic force to complete the opening operation. After the display assembly 2 is opened, release the button 4. The button 4 will slide back to its original position under the action of the spring. This will not only cause the locking tongue seat 3 to flip back to its original position closer to the display assembly 2, but also allow the limit block 41 to abut against the stop block 31 again, so that the display assembly 2 can perform the closing operation next time.

[0049] The above embodiments are merely preferred embodiments of the present invention. Ordinary variations and substitutions made by those skilled in the art within the scope of the technical solution of the present invention are all included within the protection scope of the present invention.
